Key Benefits


Q:   Are the original VB.NET files altered in any way?

Your existing code is left completely intact. The new C# project is output to the new location that you specify.

Q:   Do you guarantee a 100% complete conversion?

No - our accuracy is very high, but there will be some adjustments required for all but the simplest conversions. Read the rest of the FAQ to get an idea of a few things that are not converted.

Q:   Does Instant C# convert VB6 projects to C#?

No - the most effective way to convert VB6 to C# is to first upgrade to VB.NET, and then use Instant C# on the resulting VB.NET code.

Q:   How are classic VB.NET string functions handled?

By default, Instant C# converts them to the closest .NET string method. You also have the option of leaving them as calls to the Microsoft.VisualBasic namespace, if you are depending on some of the strange quirks of the classic VB string functions.

Q:   Is VB.NET code within ASP.NET files converted?

No - VB code within ASP.NET markup is not converted.

Q:   What are the most common adjustments necessary after conversion?
